Megamonas Bacteria Identified as Potential Obesity Culprit

A recent study from Cell Host & Microbe identifies Megamonas as a possible bacteria linked to obesity based on a large-scale cohort of obese Chinese people. This study demonstrates how the bacterium increases lipid absorption, breaks down intestinal myo-inositol, and causes obesity, which may lead to future approaches for managing obesity.

Geographic Origin Plays Key Role in Tuberculosis Infection, Harvard Study Finds

For some forms of tuberculosis, the chances that an exposed person will get infected depend on whether the individual and the bacteria share a hometown, according to a new study comparing how different strains move through mixed populations in cosmopolitan cities.

New Study Links Keloid Formation to Microbiome Imbalance

A study explores the microbiome of keloids, which are treatment-resistant raised scars. Some wounds heal completely; some wounds leave a scar; and some wounds leave a noticeable raised and growing bump larger than the original wound called a keloid.

Artificial Warming Chambers Combat Chytrid Fungus in Frogs

Infectious diseases have disproportionately affected amphibians as global diversity continues to decline due to a variety of factors. An unhealthy fungus known as chytridiomycosis, or simply "chytrid," has caused the extinction of 90 amphibian species and the decline of 500 more.

Researchers Discover Link Between Neolithic Farming and Brucellosis

Scientists believe the bacterial infection brucellosis, which affects millions of people every year and causes significant harm to the welfare of livestock, may have evolved along with the development of farming. They came to this conclusion after performing analyses of ancient DNA extracted from an 8,000-year-old sheep bone, in which the Brucella melitensis pathogen was detected.
